Invariant operators for processing the results of measurements with a finite-dimensional image for increased reliability

An operator for processing data from a specific experiment is considered to transform the data into an output function. The requirement for this function to be independent of the way of presenting the input data is formalized. Some well-known methods for processing information with a finite-dimensional image are investigated for invariance.Translated from Izmeritel'naya Tekhnika, No. 6, pp. 5–6, June, 1994.
